Application May 11, 1936, Serial No. 78,990 RenewedJanuary 3, 1939 3 Claims.

This invention relates to separable slide fastener tapes, and more particularly to a two-part stop for use in detachably holding the ends of a pair of slide fastener tapes together.

In the use of slide fastener tapes of the above nature having rows of cooperating fastener elements along the opposing edges of the tapes, and in which said elements are adapted to be interlocked by the movement of a slide member, it has been found in many instances that the last element of the row at the end of a tape became loosened, and either shifted out of its proper position or was pulled off, resulting in premature separation of the ends of said tape.

One object of this invention is to provide a two-part stop of the above nature whereby the ends of the tapes will be fitted closely and neatly together in an easyand positive manner.

Another object is to provide a device of the above nature which, when clamped at the ends of the slide fastener tapes, will prevent the last fastener element from being moved out of position or pulling off.

Still another object is to provide a detachable stop of the above nature consisting of a pair of cooperating male and female members, each of which is made from a single piece of metal.

A still further object is to provide a detachable stop of the above nature which will be simple in construction, inexpensive to manufacture, easy to manipulate, compact, ornamental in appearance, and very efficient and durable in use.

With these and other objects in view, there has been illustrated in the accompanying drawings one form in which the invention may be conven iently embodied in practice.

In the drawings: I v

Figs. 17 to 21 inclusive are similar views showing the appearance of the blank after the successive steps employed in the method of making the male member of the stop.

Fig. 22 is an enlarged view of a portion of the male stop member.

Referring now to the drawings in which like reference numerals denote corresponding parts throughout the several views, the fastener e1e 15 ment tapes upon the ends of which the detachable male and female members of the improved stop are applied comprise a pair of. narrow elongated beaded fabric strips or stringers l0 and II,

each having a row of forked jaw elements l2 provided on one side with heads which cooperate with sockets on the adjacent element clamped upon the beaded edges thereof, and said rows of elements are adapted to be interlocked for connecting the tapes together by the camming action of a' tapered slide l3 mounted thereon, when it is pulled upwardly from the lower end thereof, as viewed in Fig. 1. The rows of connected elements l2 are adapted to be disengaged from each other to permit separation of the tapes by moving the slide IS in the reverse direction, all of which is in accordance with the well known practice in this art.

Each element I2 is provided with a pair of opposed jaws which are crimped inwardly upon the edges of the tapes by suitable clamping tools not shown. The slide I3 is preferably provided with a hinged finger piece I4 to facilitate the ma-- nipulation thereof, said slide preferably having a pair of parallel spaced plates l5 and I 6 adapted to embrace the rows of elements l2 therebetween. The side plates I5 and [6 are provided on both side edges with inwardly extending side flanges I! for confining the elements I! and forcing them together into cooperating engagement. 45

The detachable female and male members l8 and IQ of the stop forming the present invention are shown in Fig. 1 in assembled position applied to the bottoms of a pair of tapes III and I I. Each of the members I8 and I9 is preferably made of one piece of material, such as a blank of sheet metal, formed, and attached to the tapes according to the methods to be hereinafter described.

These methods have also been made the subject matter of two co-pending divisional applicat'ions as follows: Serial No. 107,196, filed October 23, 1936; Serial No. 136,617, filed April 13, 1937.

Female stop member The female member l3 includes a pair of pposed tape-embracing plates 23 and 2| having alined openings 22 therein which, when the mem- I her is attached to the tape, serve to facilitate the 'attachment of the tape to the edge of the article .viewed in Fig. 1. Below the clip 23 and with its axis in alinement with the line of jointure of the two rows of elements |2 on the tape edges, a hollow cylindrical socket 24 is provided. Provision is also made of a pair of slider-guiding ears 23, one of which extends upwardly from each of th plates 23 and 2| on opposite faces of the tape I3.

Male stop member The male member i3 also has opposing tapeembracing plates 23 and 21, similar to the plates 23 and 2| of the female member, and said plates 23 and 21 are likewise provided with circular openings 23 to facilitate securing the tape ii to the article to be closed. The plate 23 has an upstanding pointed prong 23 formed on its upper edge which is adapted to be passed through the tape ii and then bent over and pressed'down upon the rear surface of the plate 21 to secure said plates to the tape The plate 23 has a pair of spaced upwardly directed side plates 33 and 3| extending from its upper edge and adapted to embrace the center edge of the tape II for reinforcing the same. The lower left-hand corner 32 of the side plate 3| is preferably disposed beneath the plate 21, as clearly shown in Fig. 4. Provision is also made of a pointed prong 33, formed on the rear edge of the side part 33, which is adapted to pass through the tape ii and be bent over and pressed down upon thebuter surface of the opposite side plate 3| to firmly connect the opposing tape embracing plates 33 and 3|. The tubular edge portion 34 connecting the side plates 33 and 3| is curved and inclined outwardly slightly from top to bottom and is extended downwardly from the lower edge of these plates in the form of a cylindrical vertical tongue 33 for-cooperative engagement with the socket 24. The tongue 33 is spaced from the lower edges of the plates 23 and 21 by a slot 33 with its axis in alinement with the line of jointure of the interlocking rows of elements |2 on the tape edges above it.

The inclined tubular portion 34 extends above the last element l2 on the tape ii and is slotted, as

- at 33,tostraddle the same. 4 when in assembled position, the rolled tongue 33 of the male member l3 fits within the socket 24 of the female member 3, thereby detachably'connecting the opposing lower ends of the tapes l3 and ii. A slot 31 is provided in the meeting edges of the socket 23 to provide clearance for the side plates 33 and 3| of the male member of the stop. The upper end of the slot 33 is adapted to abut against a shoulder 33 at the bottom of said slot 31 to hold the male and female members i3 and I3 in their relative positions, as shown in Figs. 1, 3 and 4, whereby the rows of elements 12 on the opposing tape edges will be properly interlocked when the slide I3 is moved upwardly.

To permit the assembly of the male section l3 of the stop member upon a tape, having a row of spaced headed fastener elements attached thereto, with the lug 33a tightly embraced by the two lowermost fastener elements, the slot 33 is enlarged at its upper outer end to form an armate notch 33b which extends laterally into said slot 33.

Method of making the female stop member The steps in the method of making the female member l3 are illustrated in Figs. 9 to 16, inclusive. Thus, a blank of metal 43 is first stamped out into the shape shown in Fig. 9. The openings 22 and the ears 23 are completely formed in this operation. In Fig. 10,'the result of a shearing operation is illustrated, whereby a pair of opposing slots 4| and 42 are formed in the blank 43 leaving a narrow intermediate connecting neck 43. Fig. 11 illustrates the result of the next operation whereby one end of the blank 43 is acted upon by suitable forming tools to bend down portions thereof to provide a pair of sides 44 and 43 for the clip 23, which is U-shaped in cross-section so that it may be fitted over the edge of the tape l3 and be crimped thereto by closing the sides and 43 together..

Fig. 12 illustrates the' result of the next operation in which the intermediate portion of the blank 43 adjacent the clip 23 is bent up to form a pair of parallel side portions 43 and 41. In Figs. 13 and 14 the result of another operation is shown whereby the side portions 43 and 41 are closed together into tubular form to complete the socket 24 and provide the slot 31 and its bottomshoulder 33. The material of the blank 43 has also been acted upon during this step to bend up the side plates 23 and 2| into parallelism. Figs. 15 and 16 illustrate-the results-of the next step wherein the blank is bent at the neck 43 in such a manner that the clip 23 and the socket 24 will assume a position at right-angles to the side plates 23 and 2|. The final product resulting from the next and last operation is illustrated i Fi s. 3 and 4" wherein'the side plates 2s" and 2 l are shown embracing the tape in, and with the clip 23 crimped tightly to the ribbed edge of the tape l3 below and abutting the last element i2 thereon.

Method of making the male stop' member The steps in the method of making the male member II are illustrated in Figs. 17 to 21, inclusive. Thus, Fig. 17 shows a blank 43 stamped out of sheet metal by the first or blanking bperation. The openings 23, the prongs 23 and 33, the slot 33, and a portion 43 from which the tubular tongue 33 is rolled are all blanked out in the first step. The next operation results in bending down the prongs 23 and 33 at right-angles to the blank 43, as shown in Fig. 18. Fig. 19 illustrates the appearance of the blank 43 after the next step wherein the side plates 33 and 3| are bent at right-angles to each other, and the inclined tubular portion 34 and the vertical tongue 33 are partially formed.

Figs. 20 and 21 show the results of the next operation whereby the side plates 23 and 21 are bent at right-angles to eachother and the inclined tubular portion 34 and the tongue 33 are more completely formed. The tooth-like projections 33 of the tongue 33 are bent inwardly to form a blunt point 3| at the end of the tongue 33 to faci1-.

itate its insertion into the socket 2| of the female member l8.

The final appearance of the male stop member I9 is illustrated in Figs. 3 and 4, wherein the plates 26 and 21 and the side plates 30 and 3| embrace the tape H, and are pressed together firmly against the same, the prongs 29 and 33 being passed through said tape and bent over into engagement with the plate 21 and the side plate 3|, respectively. This last step completes the tubular portion 34 and the tongue 35 and also disposes the male member I9 upon the tape end with the lowest element l2 in the slot 36.

, l9 firmly causing the rows of elements l2 to be securely interlocked together. When connecting the members l8 and !9 of the slide stop, as above described, the male member l9 should be pressed downwardly with sufficient force to insure that the edge of the slot 38 of the side plates 30 and 3| engages against the shoulder 39 of the slot 31 in the member l8, thus positioning the lowest elements l2 on the tapes ID and II properly to be interengaged by the cam slide l3 during its upward movement therealong.

The curved bottom portion 52 connecting the side plates 20 and 2| of the female member l8 serves to protect the lower end of the tape l against fraying. Likewise, the curved bottom section 53 connecting the side plates 26 and 21 of the male member l9 also protects the end edge of the tape II. The clip 23 which is clamped along the edge of the tape Ill stiffens and reinforces said tape at this point and prevents loosening of the lower adjacent element l2. The side plates 30 and 3| of the male member reinforce and stiffen the tape ll adjacent the lowermost element l2, and the slot 36 prevents the lowermost element I2 on the tape II from loosening or becoming dislocated. The prongs 29 and 33 securely maintain the male member IS in proper position on the tape H. a
